Same problem found with Ben's red. Too slippery and although none pulled to lock the gun, there was a loss of accuracy due to the primer pushing the boolit before good ignition.
You need case tension, the crimp is only an assist and no amount over just a normal roll crimp is going to help and can make things worse.
A Lee factory crimp die will ruin tension because it will squeeze the brass over the boolit and spring back, sizing the boolit and then opening too much. The lead will not spring back but the brass will.
RCBS expander dies are wrong and open brass too much and too deep.
Moly will also build up in the barrel and is a bitch to clean out.
Nobody understands crimp at all and so much on the net is so wrong it makes me laugh.
Jwp and I don't get along good but he is correct here.
If 10 gr of Unique makes boolits jump, what would you do with a 330 gr and 21 gr of 296?
Of course, the 329 was made by Mattel, light for a cap gun!
